2. Lie Algebras: Definition

3. A Misconception Marius Sophus Lie Norwegian Mathematician Geometry and differential equations

4. Lie Groups Differentiable manifold Such that the operations are compatible with the smooth structure. Examples

5. How do Lie Algebras Relate to Lie Groups? Lie Algebras help us understand Lie Groups. If G is a Lie Group, the Lie Algebra of G is defined as the tangent space of the identity element of G.
